The following access points are affected if running Cisco
IOS® Software Releases 12.3(8)JA, 12.3(8)JA1 or
12.3(8)JK and are configured for web-interface management:

350 Wireless Access Point and Wireless Bridge

1100 Wireless Access Point

1130 Wireless Access Point

1200 Wireless Access Point

1240 Wireless Access Point

1310 Wireless Bridge

1410 Wireless Access Point

Cisco 3200 Series Wireless Mobile Interface Card
(WMIC)

To determine if web-interface management is enabled on a Cisco access
point, log in to the device and issue the show ip http server
status command. If the output shows either http server
status or http secure server status as
enabled, web-interface management is enabled. An example is
shown below with web-interface management enabled:

On the next line of output, the image name will be displayed between
parentheses, followed by "Version" and the Cisco IOS release name. Other Cisco
devices will not have the show version command or
will give different output.

The following example identifies a Cisco access point running Cisco
IOS Software Release 12.3(7)JA1 with an installed image name of
C1200-K9W7-M:

The web-browser interface contains management pages that are used to
change the wireless device settings, upgrade firmware, and monitor and
configure other wireless devices on the network. The web-browser interface is
enabled by default, and is indicated by the configuration command
ip http server or ip http
secure-server.

An access point running a default configuration will use the default
enable secret password for administrative access. This can be modified via the
web-browser interface tab Security > Admin Access > Default
Authentication (Global Password) or via the CLI with the configuration
command enable secret
[new_secret].

Local User List Only (Individual Passwords) allows
administrators of the access points to define a local unique username/password
database for their administrators, so that a common global password is not
shared.

A vulnerability exists in the access point web-browser interface when
Security > Admin Access is changed from Default
Authentication (Global Password) to Local User List Only
(Individual Passwords). This results in the access point being
re-configured with no security, either Global Password or Individual Passwords,
enabled. This allows for open access to the access point via the web-browser
interface or via the console port with no validation of user credentials.

Access points configured for Local User List Only (Individual
Passwords) and running non-vulnerable versions of Cisco IOS which are
subsequently upgraded to a vulnerable version of IOS are not affected by this
vulnerability as long as the configuration is not altered after the upgrade.

When considering software upgrades, also consult
http://www.cisco.com/go/psirt
and any subsequent advisories to determine exposure and a complete upgrade
solution.

In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current hardware and
software configurations will continue to be supported properly by the new
release. If the information is not clear, contact the Cisco Technical
Assistance Center (TAC) or your contracted maintenance provider for assistance.

Each row of the Cisco IOS software table (below) describes a release
train and the platforms or products for which it is intended. If a given
release train is vulnerable, then the earliest possible releases that contain
the fix (the First Fixed Release) and the anticipated date of availability for
each are listed in the Rebuild and Maintenance columns. A device running a
release in the given train that is earlier than the release in a specific
column (less than the First Fixed Release) is known to be vulnerable. The
release should be upgraded at least to the indicated release or a later version
(greater than or equal to the First Fixed Release label).

Either of the following workarounds and mitigations may be used to help
mitigate the effects of this vulnerability:

Disable Web-Based Management
To prevent the use of the web-browser interface via:
- Web-Based Management—Select the Disable
Web-Based Management check box on the Services > HTTP-Web
Server page and click Apply.
- CLI—Log in to the device and issue these
configuration commands (save the configuration upon exiting):

Configure via CLI
Enabling Local User List Only (Individual Passwords)
via the CLI rather than the web-browser interface will provide the access point
with the desired protected configuration. Log in to the device and issue these
configuration commands (save the configuration upon exiting):

Configure RADIUS/TACACS Server first
Via the web-browser interface enabling any RADIUS/TACACS+ server
within Security > Server Manager > Corporate Servers and
then performing the option of Security > Admin Access as
Local User List Only (Individual Passwords) will provide a
workaround to this vulnerability.

Cisco will make free software to address this
vulnerability for affected customers. This advisory will be updated as fixed
software becomes available. Prior to deploying software, customers should
consult their maintenance provider or check the software for feature set
compatibility and known issues specific to their environment.

Customers with contracts should obtain upgraded software through their
regular update channels. For most customers, this means that upgrades should be
obtained through the Software Center on Cisco's worldwide website at
http://www.cisco.com.

Customers whose Cisco products are provided or maintained through prior
or existing agreement with third-party support organizations such as Cisco
Partners, authorized resellers, or service providers should contact that
support organization for guidance and assistance with the appropriate course of
action in regards to this advisory.

The effectiveness of any workaround or fix is dependent on specific
customer situations such as product mix, network topology, traffic behavior,
and organizational mission. Due to the variety of affected products and
releases, customers should consult with their service provider or support
organization to ensure any applied workaround or fix is the most appropriate
for use in the intended network before it is deployed.

Customers who purchase direct from Cisco but who do not hold a Cisco
service contract and customers who purchase through third-party vendors but are
unsuccessful at obtaining fixed software through their point of sale should get
their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC
contacts are as follows.

+1 408 526 7209 (toll call from anywhere in the world)

Have your product serial number available and give the URL of this
notice as evidence of your entitlement to a free upgrade. Free upgrades for
non-contract customers must be requested through the TAC.
